Methylbenzotriazole(TTA)

Methylbenzotriazole(TTA)
【CAS】29385-43-1
Molecular formula:C7H7N3Molecular Weight:133.16
1,Usage
TTA can be used as corrosion inhibitor of copper and copper alloy, it also has corrosion inhibition for black metals. This product is absorbed on metal surface to form a thin membrane to protect copper and other metals from corrosion of air and other harmful subjects. The membrane is more uniform. When used together with MBT, the effect is better.

3,Using method:
First, dissolved with alcohol or alkali, then added into circulating water system, the dosage of 2-10mg/L is preferred. If the metal is badly corroded, 5-10 times of normal dosage should be expected.
4,Package and Storage:
25kginner liner polyethylene (PE) bag, outer plastic woven bag. Storage in room shady and dry place.
5,Safety Protection:
Acidity, avoid contact with eye and skin, once contacted, flush with water.

MBT•Na can be used as the copper corrosion inhibitor in circulating cool water system. The mechanism is due to the chemical absorption of MBT•Na on copper surface, or chelation reaction between them. The dosage of 4mg/L is preferred. This product can also be used as plasticizer and photometer for acid copper plating.
